Are there examples of matching color headstocks on large CBS headstocks strats duing this era?

Custom colour Strats from 66-71 are worth anywhere from $11,000 to 30,000 with the smaller amount for the 71.Regular colours are worth from $8,000-20,000 however my sources fail to mention anything about matching headstocks.I have seen 66 and later 60s Strats with matching headstocks so I imagine they were at least available then but I don't know if they continued 'til 71.
